Apple Inc has cut production orders in recent weeks for all three iPhone models launched in September, the Wall Street Journal reported on Monday, citing sources.

The paper said that a lower-than-expected demand for the new iPhones and Apple’s decision to offer more models has made it more difficult to anticipate the number of components and handsets the company needs.

Apple has cut its production plan for the iPhone XR by up to a third of the nearly 70 million units that suppliers had been asked to produce between September and February, the paper said.

Apple has already announced a a lower-than-expected sales forecast for the Christmas quarter.

Apple did not comment on the WSJ report.
